Patent IT-VE950033-A1 (IT)
Title: Variatore metromeccanico di coppia per velocipedi
Inventor: SCOPINICH FRANCO
Filed: 1995-09-15
Abstract: Il Variatore Metromeccanico di Coppia per Velocipedi è un dispositivo atto a variare istantaneamente e in modo continuo il valore della coppia motrice in un velocipide in funzione della resistenza incontrata: ciò permette di mantenere costante lo sforzo fisico necessario a muovere il mezzo nelle diverse condizioni di marcia, facendo variare appunto la coppia esercitata, il rapporto pedalate/giri ruota motrice e quindi la sua velocità. Il ritorno dei pedali, coadiuvato dalla decompressione della molla del variatore, determinerà un movimento molto più armonico rispetto a quello dei velocipedi tradizionali, permettendo un procedere più piacevole, una trasformazione più redditizia della spinta applicata ed un minore affaticamento del ciclista. Il movimento rotatorio del pedale P1 determina, tramite la biella B1, il moto alterno del variatore V sul suo fulcro F. La resistenza opposta a questo movimento della ruota posteriore, determinerà la compressione della molla M del variatore V e quindi l'automatica variazione della coppia esercitata, tramite la leva L, sull'ingranaggio I; la rotazione di detto ingranaggio sarà quindi minore così come minore sarà la rotazione dell'ingranaggio a ruota libera R, ad esso collegato tramite catena, e della solidale ruota motrice T. Il ritorno della molla favorirà il ritorno del pedale nella posizione di spinta e, contemporaneamente, la spinta dell'altro pedale P2 che si avvarrà di identico dispositivo variatore. Per l'assoluta economicità, solidità e semplicità costruttiva, il variatore metromeccanico di coppia per velocipedi sostituisce qualunque dispositivo che abbia finalità analoghe, come i cambi di velocità. Può infine essere impiegato in innumerevoli altri dispositivi in cui sia necessario modificare in modo continuo ed istantaneo il valore della coppia applicata.

Title: Oppladbart brønnbatteri
Inventor: CHEN KUO-CHIANG
IPC: H01M6/04
Filed: 2013-03-06
Abstract: Et batteri for bruk nede i brønnhullet konfigurert for væskebasert opplading. Batteriet kan innbefatte separat anode- og katodevæsketanker som kan etterfylles til forskjellige tidspunkter i løpet av brønnens levetid. Ved kobling av et oppladbart verktøy til batteriet, kan det opplades fullstendig i løpet av minutter. Videre muliggjør arten av væsketankene redusert batteriomfang i jevn likesom økende kraft og levetiden gis på grunn av totalt tankvolum. Således, med minimal total intervensjonstid kan forlenget levetid og oppladbar karakter oppnås for et batteri velegnet for bruk i miljøer nede i brønnhullet.

Title: Anordning for universal vannfyller med magasin for å fylle opp vannfylte beholdere der vannet forbrukes
Inventor: ULVUND TORE
IPC: A01G27/00
Filed: 2014-02-27
Abstract: For bruk av den universale vannfylleren med magasin (1) så settes rørene (4) ned i bunnen på vannbeholderen. Høyden fra bunn i vannbeholder og opp til maks ønsket vannhøyde i vannbeholderen, må være høyere en høydeforskjellen på toppen av den øverste rørbøyen (2) og topp på magasinet (1). Når man f.eks har et juletre som "drikker" av vannbeholderen (f.eks en juletrefot med vannbeholder) vil anordningen etterfylle vann fra magasinet (1) etter hvert som vannet i vannbeholderen reduseres og til magasinet er tomt. (Magasinet kan da etterfylles og overnevnte prosess fortsetter). Anordningen fungerer også ved oppfylling av vannbeholderen. Der det kan være vanskelig å komme til eller se om vannbeholderen er tom eller når den er full, dette regulerer anordningen automatisk selv så lenge magasinet (1) på anordningen har en mindre totalhøyde en høyde på maksimalt vannhøyde i vannbeholder.

Patent NO-20181605-A1 (NO)
Title: Expandable junk mill
Inventor: LEHR DOUGLAS J
IPC: E21B29/00
Filed: 2018-12-14
Abstract: A borehole mill has blades that extend radially while moving along an inclined dovetail as a result of setting down weight on a mandrel. The blades extend axially beyond the end of the mandrel so that setting down weight disables a retainer that has the blades retracted for running in. Axial displacement of the blades along respective dovetails breaks a shear pin on a follower sleeve that is spring biased off a gage ring on the mandrel such that the spring stays compressed as long as set down weight is applied and once the mill is picked up the spring pushes the blades axially along a dovetail to the radially retracted position. The mill resumes its smallest dimension for pulling out of the hole.

Title: Operating device for a double-seat valve

Filed: 1996-11-15
Abstract: PCT No. PCT/EP96/05031 Sec. 371 Date May 18, 1998 Sec. 102(e) Date May 18, 1998 PCT Filed Nov. 15, 1996 PCT Pub. No. WO97/22821 PCT Pub. Date Jun. 26, 1997The invention relates to a device for the drive system for double seat valves comprising two individually movable closure members which, in addition to the open position, can each be individually moved into a partial open position. The object of the invention is to construct a device which is easy to assemble and is space-saving and which should be able to provide externally adjustable, partial lift stops for both closure members. Said object is attained in that a piston (107) of a first individual adjustment device (1b) for the partial open position (T1) of the independently driven closure member (4) is displaceably arranged, to form a seal, externally in a drive housing (100) of the drive device (1), and a piston (108) of a second individual adjustment device (1c) for the partial open position (T2) of the dependently driven closure member (5) is displaceably arranged, to form a seal, externally in a cylindrical recess (107a) of the piston (107), which recess faces a main adjustment device (1a).
Patent PL-332962-A1 (PL)
Title: Mould closing system for and method of injection moulding under very high pressure as well as tooling for injection moulding equipment
Inventor: KUIPERS SYTZE ARNOLD
IPC: B29C45/03
Filed: 1997-10-22
Abstract: This improvement relates to a novel method of injection moulding and novel equipment which enables manufacturing of products of very large shapes usually requiring extremely high clamping forces to be generated by means of expensive hydraulic equipment systems. This requirement appeared to be the technical restriction for making such large products. The improvement also provides for a method of mould assembling when products are shaped in such a way that any removal of the product from the mould would be prevented by the complexity of its external/internal shape. The required extremely high clamping forces are now performed and maintained during the injection molding process simply by previously positioning various mould sections themselves by means of supports in heavily dimensioned strong holding means while use is made of rather common and simple hydraulic means. Moulding forces which are generated during the injection moulding process can be fully absorbed by the heavily dimensioned holding means which keeps the entire mould circumferentially enclosed as if held by a massive fist grip.

Title: Method for operating a refuse incineration plant
Inventor: SCHIRMER ALFONS
IPC: F23G5/50
Filed: 2001-10-24
Abstract: The invention relates to a method for operating a refuse incineration plant and to a regulating system, in which, after the fire has been fanned, the generation of heat is made more uniform by regulating at least one of the operating parameters refuse metering, residence time on a grate, quantitative supply of primary air and quantitative preheating of primary air. To match the operating parameters to a varying calorific value of the refuse, the calorific value of the refuse is recorded as well as the standard regulating variables and is used to adapt the regulating means. The measure used for the calorific value is, for example, the moisture content of the flue gas generated during the incineration. Consequently, there is no need for the operator to estimate the calorific value and manually adapt the operating parameters accordingly.
